The members of the group Preliminary Study Attention on the mushroom because Mushroom which can make a career income The mushrooms are foods high in protein Thus leading to such study Experiments devised ways to accelerate and increase the yield of mushroom By adopting something close to the conductors try to increase the yield of mushrooms too To save costs, the purchase of chemicals and also maintain good soil structure as well After I finished harvesting mushrooms can also be infected mushroom that is then used to grow other crops again. For this reason, the project team have brought water mixed rice flour tapioca flour. Rice starch and normal water to try to improve productivity mushroom study Try to accelerate growth and increase productivity according to the procedures and methods The study of substances were tested concept that brings out starch water to accelerate the growth and increase the productivity of mushroom. Members within the group recognizes the importance of the process that accelerates and increases the yield of mushroom. Which now have the use of chemicals in the production of mushrooms. To increase productivity in a large quantity as Gil Webber Alidhoo acid, which is extracted from fungi. But still not safe from toxins that may harm the chin falls to the consumer Members of the group took the initiative to accelerate the growth and increase productivity without a simple mushroom toxins also helps the nutrients in mushrooms that consumers get nutrition The mushrooms can be consumed safely. Implementation of this project is a boon for consumers in the conduct of daily life and the experience to subscribers who conducted the project. In practice the scientific method to solve problems in the projects. Thus was born the idea to accelerate growth. And increase the yield of mushroom With regard to safety ( Non-toxic ) and nutrition for consumers to get a mushroom .
